Question

我的网络服务存在问题。它抛出异常如下：

Error creating bean with name 'sessionFactory' defined in class path resource [ApplicationContext-datasource.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class net.sf.cglib.proxy.Enhancer
        at org.springframework.beans.factory.access.SingletonBeanFactoryLocator.useBeanFactory(SingletonBeanFactoryLocator.java:389)
        at hk.com.xxx.util.ServiceLocator.getApplicationContext(ServiceLocator.java:25)

我有以下代码显示问题：

   import org.springframework.beans.factory.BeanFactory;
    import org.springframework.beans.factory.access.BeanFactoryLocator;
    import org.springframework.beans.factory.access.BeanFactoryReference;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.access.ContextSingletonBeanFactoryLocator;

    public class ServiceLocator {
        private static ApplicationContext applicationContext;

        protected ServiceLocator() {
        }

        public static ApplicationContext getApplicationContext() {
            if (applicationContext == null) {
                BeanFactoryLocator locator = ContextSingletonBeanFactoryLocator.getInstance("applicationContext.xml");
                BeanFactoryReference bfr = locator.useBeanFactory("applicationContext");
                BeanFactory factory = bfr.getFactory();
                applicationContext = (ApplicationContext) factory;
            }
            return applicationContext;
        }

    }

            </list>

    </bean>

</beans>

ApplicationContext-datasource.xml - ＆gt;提取一个有问题的部分

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource">
            <ref bean="AS400ABC"/>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.DB2400Dialect</prop>
                <prop key="hibernate.connection.autocommit">true</prop>
            </props>
        </property>
        <property name="mappingResources">
            <list>
                <value>hk/com/xxx/bls/dao/CategoryBean.hbm.xml</value>
                <value>hk/com/xxx/bls/dao/CustomerBillBean.hbm.xml</value>
                <value>hk/com/xxx/bls/dao/MerchantBean.hbm.xml</value>
                <value>hk/com/xxx/bls/dao/MerchantBillBean.hbm.xml</value>
                <value>hk/com/xxx/bls/dao/PaymentBean.hbm.xml</value>
            </list>
        </property>
    </bean>

然后我在网上google并发现我需要在链接I have trouble setting up spring hibernate application-context.xml中提到的lib中为JDBC 4.1添加Apache Commons Pool 2.4.2和Apache Commons DBCP 2.1.1。

我不确定上述是否正确。如果是，那么现在我在 weblogic集群中部署WAR时遇到了另一个问题。它显示以下错误：java.lang.ClassCastException: net.sf.cglib.proxy.Enhancer$EnhancerKey$$KeyFactoryByCGLIB$$7fb24d72 cannot be cast to net.sf.cglib.core.KeyFactory。在我的lib中，它有asm.jar和cglib.jar，如链接http://forum.spring.io/forum/spring-projects/web/flex/65337-an-strange-error-with-net-sf-cglib-core-keyfactory中所述。

我该怎么办？我在weblogic服务器12.2.1.3上使用JDK7

无法在org.springframework.beans.factory.access.SingletonBeanFactoryLocator.useBeanFactory中初始化类net.sf.cglib.proxy.Enhancer
